The coefficient is a number that is placed in front of the variable for which It is being multiplied to. In this case it would be 5.
Constants are values that can be thought of as the opposite of coefficients in that they do not have any other variables or letters and thus they include only a number.
Their value does not change.
Answer:
259.99
Step-by-step explanation:
You look at the hundreths place and see if the number behind it is bigger than 5, and if it is then you up it by one, and if it's 4 and below then you round it to zero. In this case you up it by one and you get 269.99.
I hope this helps!!!!
Answer:

Step-by-step explanation:
The system of equations is;
-12x-13y +13z =15
7x-10y-3z = 11
7x+14y +5z = -5
